Henry V, Holy Roman Emperor

Henry was born on August 11, 1086, in Goslar, the imperial palace town in the Harz mountains that the Salian kings favored as a residence. He was the second surviving son of Emperor Henry IV and Bertha of Savoy, and for the first decade of his life he stood behind his elder brother Conrad in the line of succession ^[1].

That changed in the 1090s. Conrad rebelled against their father in Italy and allied himself with the papal party, a betrayal that led Henry IV to disinherit him. In 1098 the princes at Mainz recognized the younger Henry as heir, and in January 1099 the boy was crowned king at Aachen. Before receiving the crown he swore an oath never to take part in government against his father's will during the emperor's lifetime ^[2].

The world Henry grew up in was one of near constant crisis. His father had been excommunicated by Pope Gregory VII, had performed the famous penance at Canossa in 1077, and still faced rebellious Saxon and south German princes as well as a papacy determined to strip kings of the right to appoint bishops. Anyone asking who was Henry V, Holy Roman Emperor, must begin with this inheritance: a monarchy under siege from both its own nobles and the reformed church ^[1].

In December 1104, while campaigning with his father against rebels in Saxony, the eighteen year old Henry abandoned the royal camp at Fritzlar and joined the opposition. He argued that his oath of obedience did not bind him because his father remained excommunicate, a position the papal party was happy to endorse. Pope Paschal II released him from the oath and backed the rebellion ^[2].

The conflict that followed was short and ruthless. In late 1105 Henry lured his father to a meeting, promising safe conduct and reconciliation, then had him detained at the castle of Böckelheim. At an assembly in Ingelheim over Christmas 1105 the old emperor was pressed into surrendering the royal insignia, and in January 1106 the princes at Mainz acknowledged the son as sole king ^[1].

Henry IV escaped custody and rallied support in the lower Rhineland, where the citizens of Cologne and Liège still stood by him. A full civil war seemed likely until the emperor died suddenly at Liège on August 7, 1106. Because he died excommunicate, his body was denied consecrated burial for five years, resting in an unconsecrated side chapel at Speyer until the ban was lifted in 1111 ^[3]. The manner in which Henry V took power left a permanent stain on his reputation, and chroniclers of the period judged the son's treachery harshly even when they had opposed the father ^[2].

Those who expected the new king to hand the papacy everything it wanted were quickly disappointed. Once secure on the throne, Henry continued to invest bishops with ring and staff exactly as his father had done, insisting that the German church, whose lands and fortresses were pillars of royal power, could not simply be released from royal control ^[4].

Negotiations with Paschal II dragged on for years. In 1110 Henry marched into Italy with a large army to receive the imperial crown, and at Sutri in February 1111 the two sides struck one of the most radical bargains of the Middle Ages: the pope proposed that the church surrender all the lands and rights (the regalia) it held from the crown, and in exchange the king would give up investiture entirely. When the agreement was read aloud in St Peter's on the day set for the coronation, the assembled bishops and princes erupted in protest, since the deal would have stripped the German church of its wealth ^[4].

Henry's response was direct. He arrested the pope and the cardinals and held them for two months until Paschal, under duress, conceded the king's right of investiture and crowned him emperor on April 13, 1111. The victory proved hollow. A Lateran council repudiated the extorted privilege in 1112, reform circles branded it a heresy, and papal legates excommunicated the emperor. Among the chief Henry V, Holy Roman Emperor facts, this coerced coronation is perhaps the most notorious ^[5].

Henry's most important alliance was with England. In 1110 the eight year old Matilda, daughter of King Henry I of England, was sent to Germany with a dowry reported at 10,000 marks of silver, and the couple were married at Worms in January 1114 in a ceremony of exceptional splendor ^[6].

Matilda was crowned and took an active part in imperial government, acting as regent in Italy during parts of her husband's reign. The marriage, however, produced no surviving children, a fact with enormous consequences for both realms. After Henry's death Matilda returned to England, where her father named her his heir; English writers called her the Empress for the rest of her life, and through her second marriage to Geoffrey of Anjou she became the mother of King Henry II of England ^[6].

Contemporaries describe Henry V as intelligent, energetic, and deeply distrustful, a ruler who relied on a small circle of ministerial administrators rather than the great princes. He acted as a patron of learned men at his court, and the chronicler David the Scot was commissioned to write an account of his Italian expedition, though the work survives only in fragments quoted by later writers ^[3].

The excommunication of 1112 gave Henry's German enemies their opening. Saxony rose against him under Lothar of Supplinburg, and in February 1115 the imperial army under Count Hoyer of Mansfeld was defeated at the battle of Welfesholz. The defeat broke royal authority in northern Germany for the rest of the reign, and Adalbert of Mainz, once Henry's chancellor and now his bitterest enemy, organized the ecclesiastical opposition ^[1].

Henry spent 1116 to 1118 in Italy securing the disputed inheritance of Margravine Matilda of Tuscany, who had died in 1115 after willing her vast lands to the Roman church while also holding imperial fiefs. His absence deepened the drift in Germany, yet it also demonstrated the reach the Salian monarchy still possessed south of the Alps ^[4].

Exhaustion on both sides finally opened the way to compromise. After failed talks at Mouzon in 1119, Pope Calixtus II and the emperor reached agreement on September 23, 1122, in the Concordat of Worms. Henry renounced investiture with ring and staff and conceded free canonical election of bishops and abbots. In return the pope allowed elections in Germany to take place in the king's presence and permitted the ruler to invest the elected candidate with the regalia by the scepter before consecration. The concordat ended nearly fifty years of open war between empire and papacy, and it counts as the central achievement of the reign ^[5]. The First Lateran Council confirmed the settlement in 1123 ^[4].

Peace with the church did not mean peace at home. Henry's last years were occupied with feuds among the princes and with an ambitious foreign scheme: in 1124 he invaded France in support of his father in law, Henry I of England, only to withdraw when Louis VI of France raised an unusually large host around the banner of Saint Denis. The failed expedition brought the emperor no gains and considerable embarrassment ^[1].

In the spring of 1125 Henry fell ill, apparently with cancer according to the near contemporary account of his final illness. He died at Utrecht on May 23, 1125, aged thirty eight. His body was carried up the Rhine to Speyer Cathedral and buried beside his father, grandfather, and great grandfather in the burial church of the dynasty ^[3].

Because he left no legitimate children, the Salian line ended with him. Henry had entrusted the imperial insignia to his wife Matilda and appears to have favored his nephew, Duke Frederick II of Swabia, as successor. The princes, guided by Adalbert of Mainz, chose otherwise: at Mainz in August 1125 they elected the emperor's old enemy Lothar of Supplinburg, deliberately asserting the elective character of the German monarchy against hereditary claims ^[2].

Any balanced Henry V, Holy Roman Emperor biography has to weigh a genuine achievement against a troubling record of methods. The Concordat of Worms was a durable settlement: by separating the spiritual office of a bishop from the worldly possessions attached to it, the agreement gave medieval Europe a working distinction between church and secular authority and served as a model for similar settlements, including the English compromise of 1107 that had partly inspired it ^[5].

Yet the reign also marked a real decline in the power of the German crown. The civil wars, the loss of Saxony after Welfesholz, and the princes' free election of 1125 all strengthened the aristocracy at the monarchy's expense, a shift that shaped German politics for centuries. Historians such as Karl Leyser and, more recently, I. S. Robinson have treated the Salian century as the period in which the old imperial church system built by the Ottonians finally broke apart ^[4].

Among Henry V, Holy Roman Emperor achievements, later generations also remembered the dynastic accident of his marriage. His childless union with Matilda of England sent the widowed empress back across the Channel, where her claim to the English throne produced the civil war known as the Anarchy and, ultimately, the Plantagenet dynasty. The last Salian thus left his deepest mark not only at Worms and Speyer but, indirectly, on the history of England ^[6].
